tune your variator, get an open air filter (like k&n or UNI), change to an irridium spark plug and adjust your jet size.  Exhaust will help but Id start on the suck part of the process rather than the blow.

g has you on the right track for sure....
But yes, it will help. A good expansion chamber is mandatory when modding any......IMO
I had gotten better performance all around myself, with 3-4 mph on top end

thanks as i have done all the other mods was just wondering was it worth doing but to gain any mph on a 50cc is good.

WITH THE LC ALL YOU HAVE TO CHANGE IS THE BOSS DRIVE TO GET FROM 30MPH STOCK TO 47MPH (BOSS DRIVE CHANGE)
